WALTER I. GREGORY, or NEW YORK, N. Y.

BEAMING-TOOL.

Application filed August 27, 1915.

To all whom it may concern Be it known that I, WALTER I. GREGORY, acitizen of the United States, and a resident of New York, in the countyof New York and State of New York, have invented a new and ImprovedBeaming-Tool, of which the following is a specification.

My invention relates to the class of reamers that are adapted to reamholes of varying size, and an object of my invention, among others, isto provide a reamer of this type that shall be simple in constructionand particularly efficient in operation.

One form of reamer embodying my invention and in the construction anduse of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which- Figure1 is a side view of my improved held in a chuck. Fig. 2 is a similarview as seen from a point located at right angles. to the point of viewof Fig. 1. Fig. 3 is a detail view in cross section on plane denoted bydotted line 3.3 a detail view showing the members separated, parts beingbroken away to show construction. Fig. 5 is a view showing a slightlydifferent form of tool embodying the invention. Figs. 6 and 7 are viewsshowing other slightly different forms of devices embodying theinvention.

My improved ream'er consists of two members 4.-5 that are substantiallyduplicates one of the other, the meeting faces 6 extending in adiagonalplane with respect to the that each piecetapers gradually fromone end to the opposite end. Each of the corners of these piecescomprising the tool is formed with a cutting edge 7 as clearly shown intending lengthwise of each of the members is located in a groove 9 inthe opposite member as a means for holding the members against lateraldisplacement one with respect to the other. Slots 10 are formed througheach of the members through which screws 11 or like fastening meansextend into the opposite member and by means of which the two membersare adjustably se- Both of the members are thus adapted to be insertedwithin and held by a chuck 12 and by chang ing the position of themembers lengthwise one of another the size of the hole to be reamed maybe varied as desired.

The formation of the interengaging axis of the tool so Specification ofLetters Patent.

tongue and groove may be varied. As shown herein the tongue extends fora portion of the distance only along one member and the groove for theremainder of the distance in line with the tongue. By :this

means the two members are formed duplicates one of the other so that inconstructing the .device a number of parts are formed any two ofwhich'may'be assembled to comprise the complete tool. This constructionof the tongue and groove, and in fact other parts may be varied to agreater or lesser degree and yet be within the spirit and intent of theinvention and scope of the appended claims.

In Fig. 5 there is shown a slightly different form of device embodyingthe invention in which the'inclined faces 13-14: are disposed indifferent planes, and are inclined to a greater degree than in thedevice of the other figures, thisto adapt the tool to wider variationsin use.

In the form of the device shown in Fig. 6 the members 15-16 haveinclined meeting faces, as in the other devices, the part 15 in thisform of the device having a tongue 17 extending its whole length andfitting a groove 18 in the member 16. The operation of the device issubstantially the same as that of the other devices hereinbeforedescribed.

In the form of device shown'in Fig.7 7

there is a body part 19 having a shank 20 adapted to be secured withinany proper holder as a drill spindle or the like, and a detachablemember 21 is secured to this body part. An intermeshin-g tongue andgroove 22-23 upon these members retain them against lateral movement, asin the form of the device shown in Fig. 6, and the device is similar tothe device of 'FigJG'With the exception that the member 21 is not of thesame length as the member 19.

I claim 1. A reaming tool comprising two members of substantially equallength and having inclined meeting faces, and means for securing themembers together in difierent positions one withrespect to the other,said members being provided with cutting edges.

2. A reaming tool comprising two members of substantially equal lengthand having inclined meeting faces, interengaging parts upon the membersto prevent lateral displacement, and means for securing the memberstogether in diiferent positions members in different lengthwise thereofone with respect to the other, said members having cutting edges.

3. A reaming tool comprising two mem bers of substantially equal lengthand having inclined meeting faces, a tongue extending lengthwise alongone member engaging a groove extending lengthwise along the othermember, and means for securing the positions lengthwise each of theother, said members being provided with cutting edges.

4:. A reaming tool comprising two members of substantially equal lengthand having inclined meeting faces, means for preventing lateraldisplacement of said members one with respect to the other, each memberhaving a slot, and screws extending through said slot in one. memberinto a threaded hole in the opposite member to adjustably secure themembers together.

5. A reaming tool comprising two members duplicates each of the otherand having inclined meeting faces, and means for securing .the memberstogether, said members having cutting edges.

6. A reamingtool comprising two members duplicates each of the other,said members having inclined meeting faces, means for preventing lateralmovement of said members one with respect to the other, and means forsecuring the members together in difi'erent positions lengthwise one ofthe other, said members having cutting edges.

7. A reaming tool comprising two members duplicates each of the other,said members having inclined meeting faces and interengaging tongues andgrooves extending.

lengthwise thereof, and means for securing sald members togetherindifferent positlons lengthwise one with. respect to the other, saidmembers having cutting edges.

respect to the other, said members being provided with 1 cutting edges.

10. A reaming tool comprising two mem bers having inclined meeting facesand each member constituting substantially half of the working portionof the tool and; said members together forming a toolrectangular in formin cross section, and means for securing the memberstogether indifferentpositions one with respect to the other, said members beingprovided with cutting edges at their corners. I

11. A reaming tool comprising a plural number of members having mclmedmeetlng faces, and means for securing the mem.-

bers together in different positions one with respect to the other, saidmembers being provided with cutting edges.
